I did a random check on the accounts shared by LoyceV, but they all I check were newbies and I couldn't check their last post.
On the shared video by OP, I only watch the first video and it's about the pump a coin.
So I was think this is all about the spam message promoting yobit, can someone confirm?
There signature was ban, so this is their next option?
All those accounts were brand new, generated, I guess, by bot as you can see the similarities in the usernames.
This has nothing to do with the signature spam they had sometime ago. It difficult to blame Yobit for this as well, everyone can conduct such spam attack.
